摘要
本文以某斜拉桥为背景,利用midas civil有限元软件建立空间动力计算模型,采用非线性时程方法进行结构地震反应分析,研究了结构在E1地震作用(50年超越概率10%)和E2地震作用(100年超越概率4%)两种设防水准地震输入下的地震响应,从结果可以得出采用纵向阻尼器的漂浮体系可以满足结构抗震性能,可为同类型桥梁的设计提供参考经验。
With the background of a cable-stayed bridge,the article establishes the spatial dynamic model by using Midas Civil finite element software. The seismic response of two kinds of seismic inputs, E1 earthquake action (50 year exceeding probability 10%) and E2 Earthquake Action (100 year exceeding probability 4%), is studied by using the non-linear time-history method. The result of seismic response point out that floating system with vertical damper can benefit structural seismic performance,and can serve as a reference for the design of same type bridge.
